What this question tests

Tests product design for content curation in a trust sensitive context: balancing relevance, source credibility, and misinformation risk.

Define the user: someone wanting quick, trustworthy news updates relevant to their interests without wading through low quality sources.
Identify the core tension: personalized relevance versus source credibility, since pure engagement optimization can favor sensational, less credible content.
Propose the design: a curated news section ranking by a combination of topic relevance and publisher credibility signals, with clear source labeling.
Address misinformation risk explicitly, requiring credibility scoring and rapid correction mechanisms for flagged stories.
Define success: time spent on credible sources and reduction in flagged misinformation shares.
Confirm with the interviewer whether this is a standalone tab or integrated directly into the main feed.

Balances relevance and credibility explicitly, ranking news by a combined score of topic match and publisher trustworthiness rather than engagement alone.
Proposes clear source labeling, showing publisher name and credibility indicators directly on each story, building on lessons from past misinformation scrutiny.
Addresses rapid correction, proposing a fast flagging and fact check partnership workflow for stories that turn out to be false.
Sets a measurable goal, for example a stated increase in time spent on credible sources alongside a reduction in flagged misinformation shares.

Optimizing purely for engagement, which risks amplifying sensational or low credibility content given Facebook's past misinformation issues.
Ignoring the need for transparent source labeling that lets users judge credibility themselves.
